解决方法：

pom文件中添加依赖：

 

<dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.7.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
